Fourth graders were on the road again with Municipal Manager, Frank Heald. This time we traveled to the West Lebanon, NH Landfill and Recycling Center. It was interesting to see an active landfill and although we couldn't get too close to it, we were able to observe how trash is dumped and spread. We saw the pipes that release various gases, including methane, from deep within the landfill. Our guide told us that within a few years these gases will be used to generate electricity for the West Lebanon area. We also learned that instead of covering the day's trash with the standard 6 inches of soil at the close of every day, a gigantic tarp is unrolled via machine to cover the accumulation. In the morning it is rolled back up and business resumes. We were totally grossed out to learn why 6 inches of soil is needed as a cover in some landfills...it's because maggots can burrow only 4 inches in a 24 hour period. It's good to know that this concern is "covered"! The Recycling Center was similar in many ways to our Transfer Station, although it was much larger. We saw plastic and metal being baled and were impressed with their weights that could range from 800 to 1,200 pounds.
